UnverifiedThe tool should return a clear error message upon blocking (such as "all proxy nodes are currently rate-limited by the target host"), letting the LLM treat the failure as an unrecoverable state and thus switch strategies rather than retry.66% similarUnverifiedThe failover loop categorizes exceptions: transient errors trigger a cooldown before switching to the next key, exhaustion triggers a switch to the next key, rejection suspends that key, and only fatal errors are actually thrown.65% similarUnverifiedWhen an agent repeatedly encounters 403 or 429 errors, standard tools throw them as recoverable exceptions, causing the LLM to retry repeatedly and trigger stricter blocking.61% similarUnverifiedA retry wrapper returning the result of the last attempt is a silent failure mode: a call that failed three times becomes an ordinary return value, and the attempt count is usually stored somewhere the trace cannot see.60% similarUnverifiedFailure modes describe the reproducible ways a tool fails under specific inputs.60% similar
